Definitions

  • Optical waveguide ports 30 and 34 and alignment stops 25 and 26 are on flexible optical coupler carrier 40, as can be noted in figure 2c.
  • This particular design is exemplary only.
  • the registration of the alignment stops 24 to the waveguide end face 12 can be very precise as it is limited by mask writing precision (approximately 100 nanometer precision) or inter-mask registration (approximately 200 nanometer precision), respectively, depending on whether a single-step or sequential process steps are used.
  • alignment stops 25 and waveguide end face 30 on the flexible optical coupler 32 are used.
